The area of a circle is -

(pi)r^2 = A

We can find the diameter by first finding the radius. First we plug in the information we already know.

(pi)r^2 = 2.6

Then we divide both sides by pi to isolate 'r'.

r^2 = .83

We take the square root of both sides.

r = .91

Since the diameter is twice the radius we multiply the radius by 2.

.91(2) = 1.82

The diameter of the circle is 1.82 units.
